Abstract

Methods and apparatuses are provided for wireless communication. A scheduling message including resource allocation information to allocate a resource for uplink transmission, is received. Data and a pilot are transmitted via the allocated resource for uplink transmission. An ACK/NACK resource is identified based on an index of the allocated resource for uplink transmission and information associated with the transmitted pilot. An ACK/NACK signal is received in response to the transmitted data using the identified ACK/NACK resource.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method for wireless communication, comprising:
 receiving a scheduling message comprising resource allocation information to allocate one or more resources for uplink transmission; 
 transmitting data and a pilot via the allocated one or more resources for uplink transmission; 
 identifying an ACK/NACK resource based on an index of the allocated one or more resources for uplink transmission and other information included in the scheduling message; and 
 receiving an ACK/NACK signal in response to the transmitted data using the identified ACK/NACK resource, 
 wherein the ACK/NACK resource is identified by an ACK/NACK channel group and an orthogonal sequence within the ACK/NACK channel group. 
 
     
     
       2. The method of  claim 1 , wherein the other information is information on multi-user multi-input multi-output (MU-MIMO). 
     
     
       3. The method of  claim 1 , wherein the index is a lowest index from among one or more indexes of the allocated one or more resources for uplink transmission. 
     
     
       4. The method of  claim 1 , wherein the other information is related to the pilot. 
     
     
       5. The method of  claim 1 , wherein the ACK/NACK channel group comprises a plurality of resource element groups and each resource element group comprises a plurality of resource elements. 
     
     
       6. The method of  claim 5 , wherein the plurality of resource element groups has a cell-specific offset. 
     
     
       7. An apparatus for wireless communication, comprising:
 a transmitting and receiving unit for receiving a scheduling message comprising resource allocation information to allocate one or more resources for uplink transmission, transmitting data and a pilot via the allocated one or more resources for uplink transmission, and receiving the ACK/NACK signal in response to the transmitted data; and 
 a controller for identifying an ACK/NACK resource based on an index of the allocated one or more resources for uplink transmission and other information included in the scheduling message, and controlling the transmitting and receiving unit to receive the ACK/NACK signal using the identified ACK/NACK resource, 
 wherein the ACK/NACK resource is identified by an ACK/NACK channel group and an orthogonal sequence within the ACK/NACK channel group. 
 
     
     
       8. The apparatus of  claim 7 , wherein the other information is information on multi-user multi-input multi-output (MU-MIMO). 
     
     
       9. The apparatus of  claim 7 , wherein the index is a lowest index from among one or more indexes of the allocated one or more resources for uplink transmission. 
     
     
       10. The apparatus of  claim 7 , wherein the other information is related to the pilot. 
     
     
       11. The apparatus of  claim 7 , wherein the ACK/NACK channel group comprises a plurality of resource element groups and each resource element group comprises a plurality of resource elements. 
     
     
       12. The apparatus of  claim 11 , wherein the plurality of resource element groups has a cell-specific offset. 
     
     
       13. A method for wireless communication, comprising:
 transmitting a scheduling message comprising resource allocation information to allocate one or more resources for uplink transmission; 
 
       receiving data and a pilot via the allocated one or more resources for uplink transmission;
 identifying an ACK/NACK resource based on an index of the allocated one or more resources for uplink transmission and other information included in the scheduling message; and 
 transmitting the ACK/NACK signal in response to the received data using the identified ACK/NACK resource, 
 wherein the ACK/NACK resource is identified by an ACK/NACK channel group and an orthogonal sequence within the ACK/ NACK channel group. 
 
     
     
       14. The method of  claim 13 , wherein the other information is information on multi-user multi-input multi-output (MU-MIMO). 
     
     
       15. The method of  claim 13 , wherein the index is a lowest resource index from among one or more indexes of the allocated one or more resources for uplink transmission. 
     
     
       16. The method of  claim 13 , wherein the other information is related to the pilot. 
     
     
       17. The method of  claim 13 , wherein the ACK/NACK channel group comprises a plurality of resource element groups and each resource element group comprises a plurality of resource elements. 
     
     
       18. The method of  claim 17 , wherein the plurality of resource element groups has a cell-specific offset. 
     
     
       19. An apparatus for wireless communication system, comprising:
 a transmitting and receiving unit for transmitting a scheduling message comprising resource allocation information to allocate one or more resources for uplink transmission, receiving data and a pilot via the allocated one or more resources for uplink transmission, and transmitting the ACK/NACK signal in response to the received data; 
 a channel decoder for decoding the received data; 
 an ACK/NACK generator for generating the ACK/NACK signal corresponding to the decoded data; and 
 a controller for identifying an ACK/NACK resource based on an index of the allocated one or more resources for uplink transmission and other information included in the scheduling message, and controlling the transmitting and receiving unit to transmit the generated ACK/NACK signal using the identified ACK/NACK resource, 
 wherein the ACK/ANCK resource is identified by an ACK/NACK channel group and an orthogonal sequence within the ACK/NACK channel group. 
 
     
     
       20. The apparatus of  claim 19 , wherein the other information is information on multi-user multi-input multi-output (MU-MIMO). 
     
     
       21. The apparatus of  claim 19 , wherein the index is a lowest index from among one or more indexes of the allocated one or more resources for uplink transmission. 
     
     
       22. The apparatus of  claim 19 , wherein the other information is related to the pilot.
